    Rated 5 out of 5 by from Best Bang for the Buck I'm thoroughly impressed with this ecm/harness. I had to learn about my lb/hr, CID, 24x knock, and it fired right up!!! This will be my first purchase for my next LS swap!

    Rated 3 out of 5 by from Not bad, but far from good I’ve had my fitech 70050 in my ls swapped fc rx7 for about three months now. The harness is very clearly labeled with quality connectors. Initiating setup is very easy, very simple to get the car started, and the self learning works great. However, there are many downsides. First off, you are limited to four guages, and there is lno way to send data to a tablet or computer for more gauges. There is also a severe lack of features. There is no two step/ antilag and no flex fuel/ ethanol content features. Fitech customer service is poor to say the least, took 5 days to get an email back. Ultimately this is a good fuel injection kit for the average guy with a mild ls swap, but for those who want more from there engine management, this isn’t not for them.

    I am planning on putting a 4-speed Muncie behind a 5.3 vortec motor. Will I need to add a vehicle speed sensor for this system to work on my car?

    Asked by: TheQuestioner47
    You should not need a speed sensor with the Muncie manual transmission.

    Does this kit come with hand controller as per other FiTech kits? What is the best price, including getting it shipped to Australia in au $? Thanks

    This is a stand alone kit and does not include the transmission controller. This will have the ECU controller. You can add this kit to your shopping cart and checkout with your address to get your total price with shipping included.
